British motor racing star Lewis Hamilton has been fined A$500 (£288) for "behaving like a hoon" and performing boy-racer stunts in Melbourne.

The Formula One driver had been caught by police executing a "burnout" and "fishtail" – tricks in which wheels are intentionally spun and skidded – in front of fans two days before the Melbourne grand prix back in March.

The 25-year-old was not in court to hear his punishment today. But his lawyer, Sandip Mukerjea, said Hamilton would plead guilty to the charge of improper use of a motor vehicle. He avoided conviction as it was a first offence, but will be forced to pay the fine.

Mukerjea said his client suffered "embarrassment, humiliation and distress" as a result of the incident. Hoon is a derogatory term used in Australia and New Zealand, to refer to a young person who engages in loutish, antisocial behaviour.

Hamilton fell foul of the state of Victoria's so-called "hoon" laws, which target youthful loutish behaviour, on 26 March, two days before the race. The driver was in a borrowed Mercedes when he was seen performing stunts outside the grand prix track at Albert Park, Melbourne.

The car was impounded by state authorities. It marked the low point in an unhappy race meet for the British driver. Starting 11th on the grid, he made his way through the field only to be bumped off the track by Australian Mark Webber with two laps remaining. He finished the race in sixth place.

Hamilton is due to compete in the Belgian grand prix this weekend and wrote twice to the court to explain his absence.

Magistrate Clive Alsop said the British racing driver was a role model to young people and as such should have known better. "This is about somebody in a responsible position behaving like a hoon," he added.
